Firstly mix the flour with the ground almonds and set aside. At this time we can go preheat the oven to 200°C.
Separate the white from the yolk of the four eggs, beat the whites until stiff and pour the sugar gradually.
When the whites are well beaten with the sugar add in this order the egg yolks, the flour and almonds mixture, the cottage cheese and the baking powder. Mix well.
Take a baking pan, spread the butter so the cake doesn’t stick and pour the mixture. Put it in the oven at 200°C about 30-40min.
After this time take it out of the oven, let cool slightly and serve with some icing sugar.
